Stuffed Pepper Casserole Ingredients
• All you need for deliciousness!
For the Base
- Lean Ground Beef – The heartiness is key, but ground turkey works beautifully for a lighter meal.
- Bell Peppers – Choose vibrant colors to add sweetness and visual appeal; a mix makes it pop!
- Onion – For that essential depth of flavor; any variety will do great (yellow, white, or red).
For the Flavor
- Italian Seasoning – A blend of classic herbs, perfect for complementing the meat; dried can substitute if needed.
- Sea Salt – It enhances the dish’s flavors; remember to adjust based on your broth’s sodium level.
- Black Pepper – Adds a touch of warmth and complexity; always go for freshly ground for the best taste.
- Garlic – Use minced for a bigger punch of aroma and flavor; fresh is fabulous, but powder works in a pinch.
For the Sauce
- Beef Broth – This adds moisture and rich flavor; for a vegetarian option, go with vegetable broth.
- Diced Tomatoes – They brighten the casserole with acidity and moisture; fire-roasted varieties are a delicious upgrade.
- Tomato Sauce – The binding agent that creates a rich base; homemade is great if you have it on hand.
- Soy Sauce or Worcestershire Sauce – Introduce a savory umami kick; it’s optional, but highly recommended!
For Texture
- Uncooked Rice – Absorbs all the flavors; white basmati is my go-to for texture, but feel free to experiment with brown rice.
For the Topping
- Shredded Cheddar Cheese – This magical layer creates a delicious, gooey texture; for variety, consider using mozzarella for a different flair.

Step‑by‑Step Instructions for Stuffed Pepper Casserole
Step 1: Brown the Meat and Onion
In a large pot or Dutch oven, heat a drizzle of oil over medium-high heat. Add 1 pound of lean ground beef and diced onion, cooking until the beef is browned and fully cooked, about 5-7 minutes. Stir occasionally, breaking the meat into smaller pieces. Once done, drain any excess grease to prevent a greasy Stuffed Pepper Casserole.
Step 2: Sauté Garlic and Bell Peppers
Next, mix in minced garlic and diced bell peppers into the pot. Continue cooking for about 5 minutes, stirring occasionally, until the garlic is fragrant and the peppers have softened slightly. You’ll notice the vibrant colors brightening! This adds essential flavor and aroma to your Stuffed Pepper Casserole.
Step 3: Season the Mixture
Stir in Italian seasoning, sea salt, and freshly ground black pepper. Mix well to ensure the spices coat the meat and vegetables evenly. This should take about 1 minute. The seasoning will enhance the flavors of the casserole, creating a delicious base for your dish.
Step 4: Add the Sauce Ingredients
Incorporate 1 can of tomato sauce, 1 can of diced tomatoes, soy sauce or Worcestershire sauce, and beef broth into the mixture. Bring everything to a gentle boil over medium-high heat, stirring occasionally. This should take about 2-3 minutes, allowing the flavors to meld beautifully in your Stuffed Pepper Casserole.
Step 5: Mix in the Rice
Once boiling, add 1 cup of uncooked rice and give it a good stir. Reduce the heat to medium-low, cover the pot, and let it simmer for approximately 15 minutes. Keep an eye on the liquid level and adjust as necessary; the rice should be tender and absorb all those savory flavors in the casserole.
Step 6: Melt the Cheese
Remove the pot from heat and mix in 1.5 cups of shredded cheddar cheese until melted and creamy. For an extra cheesy Stuffed Pepper Casserole, sprinkle additional cheese on top. The heat will help melt it further, making for a deliciously gooey texture everyone will love.
Step 7: Finish Baking Optionally
For a golden brown finish, transfer the mixture to a casserole dish if desired. Bake at 350°F for about 10-15 minutes until the cheese is bubbly and lightly browned. If staying on the stovetop, allow the cheese to melt and form a delightful crust.
Step 8: Serve and Enjoy
Serve your warm Stuffed Pepper Casserole hot, garnished with fresh herbs if you like. This hearty dish pairs wonderfully with a side salad or some crusty garlic bread, perfect for a cozy family meal!

Easy Stuffed Pepper Casserole Recipe FAQs
How do I choose the right bell peppers?
Absolutely! When selecting bell peppers, look for ones that are firm and shiny, avoid any with dark spots or wrinkled skin. Vibrantly colored peppers (red, yellow, and orange) are sweeter than their green counterparts. A mix not only tastes great but also makes for a visually appealing dish!
How should I store leftovers of the casserole?
Very simple! Store any leftovers in an airtight container in your refrigerator, and they’ll be good for up to 5 days. Make sure to reheat on the stovetop or in the oven, covered, for about 15-20 minutes at 350°F to keep them moist and delicious.
Can I freeze the stuffed pepper casserole?
Yes, you can! To freeze, allow the casserole to cool completely, then transfer it to an airtight container or freezer-safe dish. It can be frozen for up to 3 months. To reheat, thaw it overnight in the fridge, then warm in the oven at 350°F for 25-30 minutes.
What should I do if the rice isn’t cooking properly?
Don’t worry; this can happen! If you find the rice is still crunchy after simmering, add a splash more broth or water and continue cooking on low heat, covered. Keep an eye on it and check every 2-3 minutes until it reaches the desired tenderness.
Is this casserole suitable for dietary restrictions?
Absolutely! To make it a vegetarian dish, substitute the ground beef with lentils, quinoa, or a plant-based meat alternative. Be sure to check ingredient labels for potential allergens, such as soy sauce, which may contain wheat. Always customize to fit your family’s dietary needs.
